Summary of wheelchair climbing stairs
Wheelchairs are an indispensable means of transportation for the elderly and infirm as well as those with lower limb disabilities. With the increase of barrier-free facilities, the range of activities of wheelchair users has gradually increased, but the stairs have greatly restricted the wheelchair. Stair-climbing wheelchairs can be divided into three types according to their transmission modes: star wheel type, crawler type, and step support type.
Wheelchairs and electric wheelchairs can drive on flat roads with a slope of fewer than 12 degrees, but they cannot cross the stairs when they encounter them. At present, nearly half of the urban residents in China still live in buildings with no elevators below the 7th floor, and they often need a strong person to walk downstairs or four people in a wheelchair to go downstairs. This situation has brought inconveniences to countless people with disabilities and the elderly, and even in some families, due to insufficient nursing staff, it is rare for the disabled at home to go downstairs several times a year. Because of this, the electric stair-climbing wheelchair can help a disabled or elderly person weighing more than one hundred kilograms to go up and down the stairs freely under the operation of any adult.
